YouTube is celebrating 10 years of cat videos and Downfall parodies this month, and to celebrate, The Daily Conversationput 101 of the site's most important, funniest and worst viral videos into this supercut.

It's a great look back at the decade of one of the internet's biggest sites; it's also a 16-minute primer on some of the 'net's biggest in-jokes. After watching the supercut, you can also see all the videos in one post, which sounds like a great way to get nothing at all done this weekend. [TDC via Wired]
